Juggling in Movies

Sam 'Ace' Rothstein, a mob-connected casino operator in Las Vegas,
attempts a civilized lifestyle with his money-conditional wife, Ginger.
Nicky Santoro, a boyhood friend of Ace and now a Made-Man of the Mafia,
arrives in town with an ambitious agenda of his own that soon disrupts
Ace's life. Before long, Ginger and her long-time leeching lover
Lester, along with Nicky's mistakes, cause problems.

Robert DeNiro juggles three white balls for about 15 catches. Using
several edits, he may have only gotten 4 or 5 throws at a time. The
scene ends with him chasing the balls around the Las Vegas stage he's
on. The credits list the excellent professional juggler Gil Dova, who
may have only been used to teach DeNiro to juggle.
